You can create up to 300 distribution lists in your Hosted Exchange Email account for each of your organizations. All users in your organization can send email messages to these lists. For each distribution list, you can designate members of that list as owners who can manage it.
You can add and remove contacts from the distribution lists by editing them in Outlook®. For instructions on using Outlook to add or remove contacts from distribution lists, see Populating Distribution Lists in Outlook Exchange Email.
You can create a variety of distribution lists that all users in the organization can use.
Owners of distribution lists can change the name or domain of a distribution list. Changing the domain changes the address of the distribution list. Owners can also add or remove other owners of the distribution list.
When you delete a distribution list it is no longer available to the users in your organization.
